In this image provided by NASA this is the STS-48 onboard photo of the Upper Atmosphere Research Satellite (UARS) in the grasp of the RMS (Remote Manipulator System) during deployment, from the shuttle in September 1991. The satellite is 35 feet long, 15 feet in diameter, weighs 13,000 pounds. U.S. space officials say they expect a dead satellite to fall to Earth in about a week. NASA has been watching the 6-ton satellite closely. NASA scientists are doing their best to tell us where a plummeting 6-ton satellite will fall later this week. It's just that if they're off a little bit, it could mean the difference between hitting Florida or New York. Or, say, Iran or India. (AP Photo/NASA)
